Ultimate Guide to Worcester Oil Boilers

There are approximately four million homes which do not have a connection to the main gas network. Of these around one and a half million homes use an oil-based heating system.

Oil Fired Central Heating: How does it work?

An oil-based system of heating delivers heat in the following ways:

Radiators heated via steam
Vents emitting warm air
Hot water provided through baseboards

The system uses a thermostat to detect if the temperature in the room falls below the temperature it has been set to. When this happens, a signal gets sent to the heating system so heat is generated for your home.

Sequence of how it works:

The boiler activates
A pump transfers oil from the storage tank
The oil is made into a mist and combined with air and pushed into the burner and the combustion chamber ignites the mixture.

Heating System Types

Warm air systems and Water-based work in different ways. There are two main types of water-based systems. These are steam systems and hot water systems.

In the water-based system:

Water gets heated in a steel or cast-iron boiler and is then distributed around the home.
In hot water systems, heated water circulates through radiators or baseboards
In a steam system, water turns to steam before rising through the piping to the radiators.

In the warm-air type of system:

The air gets heated by a furnace
The blower component pushes heated air via ducts, and it comes out through vents in your home’s floors or walls.
Air is pulled back into the furnace via a return duct. This operates on a continuous cycle.
Waste gases created by combustion exit the system and your home by via a flue pipe.

If You are Thinking of Switching to an Oil Heating System

Oil bases heating systems offer comfort and economic benefits. However, it is important that you carefully assess conversion costs before you make the decision to switch.

Costs of Conversion to an Oil Heating System

Below you will find a checklist that will aid you is assessing comfort and economic benefits against the cost of switching to an Oil based heating system.

Tank removal and disposal estimates of costs.
Comparable new heating system costs and the fuel type.
Efficiency ratings and associated heat output of the systems.
Cost of installation.
Price of fuel for the system.
Distribution charges / delivery charges.
Assess the fuel providers for your area. Are they a business that keeps to their commitments?
If your neighbours use an oil-based system:
- Are they happy with their provider?
- Could you save delivery costs by having a delivery at the same time?

Installing Central Heating Costs

Replacing/Upgrading your heating system has the potential to save you hundreds in a year. With the exception of laying of pipework for the heating system it is a straight-forward activity for a qualified-installers.

As part of your installation it is very advisable to have zoned heating controls. These controls if chosen break the areas of your home into different zones for heating. Each floor of your property would be split into a zone with the system providing heating to particular floors at defined times.

Oil Central Heating: The Positives

Oil’s high efficiency gives a good return for every unit of energy
Modern condensing boilers make use of the hot flue gases. They are therefore 90% more efficient than standard boilers.

Oil Central Heating: The Negatives

Based on demand the price of oil for a heating system can fluctuate. It is also susceptible to things such as political unrest.
Due to oil being a road-based delivery system you have the potential to run out before you can get your next shipment. To avoid this issue, you have to plan your order ahead of your actual need.
Condensing oil-based boilers are for the most part floor standing. These require plumbing in order to allow acidic condensate fluid to be drained away.
